The chicken I make vs. the chicken I get at a restaurant are not even in the same ball park. Can someone teach me how to prepare and cook chicken so it A.) has flavor and B.) doesn't require enough dipping sauce to fill a pool just to swallow it?

Please help! I just want to make chicken that is tasty AND healthy. I really only use the chicken to put on my salads but occasionally eat it plain or on a sandwich. Thanks!
